Drivers_MKS_TMC2209

Tmc2209 have all function of tmc2208,can completely replace tmc2208. At the same time, tmc2209 have better heat dissipation, support bigger current, support sensorless-homing function.

How to buy

• MKS TMC2209 on Aliexpress MKS TMC2209

Video Tutorials

• MKS TMC2209 V2.0 used on MKS Robin E3D. It can be referred to Use tutorial

Notice

• TMC2209 default direction opposite to A4988/DRV8825, if you change from A4988 to TMC2209 ,maybe need edit fireware

  • Configuration.h:#define INVERT_X_DIR false-->true or true-->false

• If you don't use sensorless-homing function, remove jumper cap from DIAG on the motherboard

Dir/step mode set

• Setting method of jumper cap can be referred to Use tutorial,microstep setting recommend 16.

 MKS TMC2209
M0  | M1  | Microstep Setting
GND | GND | 8 microsteps
VCC | GND | 32 microsteps
GND | VCC | 64 microsteps
VCC | VCC | 16 microsteps
 GND = Jumpers open               VCC = Jumpers connection

• Driver current regulation
  • Verf measures the voltage of Gnd and potentiometer middle
  • Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive
  • Please connect the power supply when measuring voltage as well, do not connect only the USB power
  • I=Vref Default I=1.25A

Uart mode set(take X axis as example)

• Setting method of jumper cap can be referred to Use tutorial

     O O O  M0
     O O O  M1
     O=O O  M2
     O O 
  

• Uart mode firmware set

  • Enable EEPROM to store parameters set by LCD

    • Configuration.h:#define EEPROM_SETTINGS

  • Enable uart mode

    • Configuration.h:#define X_DRIVER_TYPE TMC2209

  • Set current and microsteps

    • Configuration_adv.h:#define X_CURRENT 800 //Set current to 8001.414 ma,peak current=Value1.414
    • Configuration_adv.h:#define X_MICROSTEPS 16 //Set MICROSTEPS, 16 recommended

  • Enable low-speed Stealthchop, high-speed Spreadcycle

    • Configuration_adv.h:#define HYBRID_THRESHOLD //enable HYBRID_THRESHOLD
    • Configuration_adv.h:#define X_HYBRID_THRESHOLD 100 //Set the speed of mode conversion

• Uart mode test

  • You can send to the board M122 test uart mode is ok or not(need enable #define TMC_DEBUG in configuration_adv.h file). If not ok, you will get nothing, if ok, you will get info like this:

    Testing X connection... OK
    Testing Y connection... OK
    Testing Z connection... OK
    Testing E connection... OK
    

  • Note: You must use DC12-24V power supply, not just USB power supply. Otherwise, TMC will report an error

• Change parameter and save

  • By LCD12864:

    • Change parameter: Configuration -> Advanced Settings -> TMC Drivers
    • Save parameter: Configuration -> Store Settings
    • Load parameter: Configuration -> Load Settings

  • By MKS TFT35:

    • Change parameter: Settings -> Config -> Motor -> TMC currentsetting
    • Save parameter: Settings -> Config -> Gcode send M500
    • Load parameter: Settings -> Config -> Gcode send M501

  • By repetier(Pronterface..):

    • Send M906 setting current, for example, M906 X500 setting x-axis current is 500ma
    • Send M500 save parameter
    • Send M501 load parameter

Sensorless-homing Set(take X axis as example)

• Setting method of jumper cap can be referred to Use tutorial

  • Jumper cap set uart mode
  • Jumper cap set "Drive IC Power:3.3V"
  • Jumper cap set "X-"

• Sensorless-homing firmware set

  • First you need finish uart mode firmware setting,after that, you need set:1.Change CHOPPER_TIMING CHOPPER 2.Enable Sensorless_homing 3.Change X_STALL_SENSITIVITY

  • Set the default voltage to DC supply voltage

    • Configuration_adv.h：#define CHOPPER_TIMING CHOPPER_DEFAULT_12V //According to DC supply

  • Set Enable SENSORLESS_HOMING

    • Configuration_adv.h：#define SENSORLESS_HOMING

  • Set blocking threshold,more bigger more sensitive

    • Configuration_adv.h：#define X_STALL_SENSITIVITY 125 //According to your 3d printer
